ofc Nordeus should take some share from betting. It's their interes.
there are some examples
1. me and my friend are in same league, (I'm on 1st place) so we want to add some interest of our el clasico, I bet 5 token, he bets 5 too, winner takes 8-9 token and nordeus gets for it's service 1-2 token. same with $
2. nordeus announces betting scores for each game in your league/cup/chemp cup. and you can bet on other teams $ only. as normal bookmaking works.
3. you can bet on only the games which your friends are taking place.
(sry for english, idea is clear I think)
